I'm on day 656 and refuse to go back. The shit smells filthy to me now.

Be careful with chantrix I heard people get hooked on that and they just trade one addiction for another.

My winning formula for quitting smoking after 10 years+ pack a day habit.
I switched to chew for a while. Skoal straight long cut. This is how I fed the physical craving for nicotine. After a while I slowly cut back on the chewing where I got down to 1 dip a day in the evening. Eventually I started going a few days between dips and then quit chewing. I didn't smoke in the house so that was easy enough. There are a few trigger moments such as after a meal, in the car, or after an xxx encounter with the woman. Behavior modification is the name of the game. Recognize the urge and knowingly disregard it. Eventually it becomes second nature.

I made sure to get drunk a few times at home to train for when I hit the smoke filled bar. I always ****ed up before when I was drunk. I graduated when I got totally shitfaced at the bar and didn't bum a smoke from anyone. Now the shit seems so filthy I can't believe I smoked as long as I did.
